Kernrechtsfrage
Whether the change of use to a massage salon required a building permit and fire-safety review.
Extrahierter Entscheid
Yes. A change of purpose is permit-required, and fire-safety compliance must be reviewed even without structural alterations.
Extrahierte Begründung
Under cantonal building law, purpose changes are permit-relevant; fire-safety duties apply to industrial and commercial buildings and are assessed according to the VKF standards.
